Definitions
- the present invention relates to a dielectric composition with mineral oil base for electrical equipment with absorption of improved gas.
- Mineral oils are widely used as oils insulators in various electrical materials such as transformers, capacitors, and cables.
- mineral oils include natural compounds different such as paraffin chains, cyclic compounds saturated naphthenic, aromatic structures whose polyaromatic condensed.
- Aromatic compounds give mineral oils better dielectric properties such as better breakdown voltage or so-called gassing properties.
- the absorption of gas is characteristic of the behavior of a oil under high electric field.
- the oil can either produce more gas in which case it is called “gas-evolving” (gas producer), or absorb hydrogen, it is then called “gas-absorbing” (absorber of gas).
- Condensed polyaromatics are diverse and varied in nature, but most are considered carcinogenic. Also, in order to reduce the polyaromatic content in mineral oils, these undergo a hydrogenation treatment. This treatment however has the disadvantage of making others disappear completely aromatic considered as not very toxic.
- the Applicant has found that the use of small amounts of compounds of the polyarylalkane family made it possible to improve the gas absorption property of mineral oils.
- the compositions (I) may contain product (A) with 2 rings, (methylbenzyl) xylene, and product (A) with 3 rings which is designated by bis (methylbenzyl) xylene.
- compositions (I) usable according to the present invention mention will be made of the polyarylalkane composition sold by ELF ATOCHEM S.A. under the designation JARISOL XX having a content by weight of compounds with 2 and 3 aromatic rings greater than 99%.
- compositions can be obtained by methods described in patents EP 136 230-B1, EP 299 867-B1, EP 384 818-B1, EP 500 435-B1 incorporated in the present invention, by references, which consist of chlorinating toluene or xylene and then to perform a Friedel and Crafts type condensation either on toluene, either on xylene (mixture of isomers), or on a toluene and xylene mixture, either on benzene or on a mixture benzene and toluene.
- the reaction is finished, the or reagents not transformed by distillation then the crude product can be subjected to a dechlorination treatment as described in the patent EP 306 398-81.
- compositions (II) can be obtained by a process described in patent EP 136 230-B1 which consists, in a first step, in reacting chlorine on toluene by radical reaction in the presence of free radical generator at a temperature between 50 ° C and 110 ° C then in a second step, the reaction product from the first step is subjected to a condensation reaction with toluene in the presence of FeCl 3 at a temperature between 50 ° C and 100 ° C.
- compositions (I) can be obtained according to a process described in patent EP 0 50 435-B1 which consists in carrying out the condensation of (methyl) benzyl chloride with xylene in the presence of FeCl 3 .
- the dielectric compositions according to the invention have the advantage of having improved gas behavior (improved gassing).
- the interface between a column of liquid and a volume of hydrogen is subjected to electrical discharges between 2 electrodes placed at different potentials.
- the evolution of the gas volume is monitored as a function of time.
- the gassing expressed in ⁇ l / min, is positive if gas is released and is negative if gas is absorbed.
